What are the 5 characteristics of echinodermata?
Characteristics of Echinodermata
- They have a star-like appearance and are spherical or elongated.
- They are exclusively marine animals.
- The organisms are spiny-skinned.
- They exhibit organ system level of organization.
- They are triploblastic and have a coelomic cavity.
- The skeleton is made up of calcium carbonate.
What is a unique characteristic of echinoderms?
Echinoderms possess a unique ambulacral or water vascular system, consisting of a central ring canal and radial canals that extend along each arm. Water circulates through these structures and facilitates gaseous exchange as well as nutrition, predation, and locomotion.
What are the characteristics of echinoderms for kids?
Echinoderms have these features:
- A skeleton of plates. These are formed from calcite, a mineral made of calcium carbonate.
- Five-rayed (pentameral) symmetry.
- A water-vascular system. This is an internal system of tubes and bladders filled with water.
- Tube feet.
- Stenohaline.
- Entirely marine.
What is the classification of Echinodermata?
Echinodermata
Echinoderm/Scientific names
What are the 5 classes of phylum Echinodermata?
The phylum echinoderms is divided into five extant classes: Asteroidea (sea stars), Ophiuroidea (brittle stars), Echinoidea (sea urchins and sand dollars), Crinoidea (sea lilies or feather stars), and Holothuroidea (sea cucumbers).
What are the defining characteristics of echinoderms quizlet?
echinoderm
- A Water Vascular System: fluid filled canals derived from a pair of coelomic compartments servicing numerous flexible feeding and locomotory appendages (tube feet)
- Pentamerous (5-pointed) radial symmetry in adults.
- Calcareous ossicles derived from mesodermal tissue forming an endoskeleton.
What are the characteristics that distinguish echinoderms from other phyla?
What characteristics distinguish echinoderms from other invertebrates? Their rough shiny appearance; water vascular system, bilateral larvae turns radially symmetrical when adult. And in statfish “skin gills” for respiration and excretion. List three examples of the phylum Echinoderma, other than the starfish.

What are the general characteristics of Mollusca?
Characteristic Features of Phylum Mollusca
- They are bilaterally symmetrical.
- They are triploblastic, which three layers.
- They show organ system grade of organisation.
- The body is soft and unsegmented.
- Body is divisible into three regions – head, a visceral mass, and ventral foot.
- Body is covered by a mantle and shell.
What classification is phylum echinodermata?
What characteristics do all echinoderms have in common?
All echinoderms share several common characteristics despite very dissimilar outward appearances differentiating them from all other members of the animal kingdom. First, they all possess five-part radial symmetry around a central disk. Second, they all possess a very unique water vascular system (vascular system based on water).
What does Echinodermata literally mean?
The name echinoderm literally means “spiny skin.”. Echinoderms are characterized by their pentaradial symmetry, internal skeletons, a water vascular system, and tube feet. The phylum Echinodermata is split into 5 main classes.
What are the similarities between Chordata and Echinodermata?
Similarities Between Echinoderms and Chordates Echinoderms and chordates are two closely-related groups of animals. They show bilateral symmetry at any stage of their life cycle. Therefore, they belong to the clade Bilataria. Also, both are deuterostomes whose blastopore develops into the anus. And,
What are three examples of echinoderms?
Examples of an echinoderm include a starfish, a sand dollar, a brittle star, a sea urchin, and a sea cucumber. There are around 7,000 echinoderm species, and they can range from less than an inch to over three feet in diameter.
